C#写日志类实例

本文实例讲述了C#写日志类，分享给大家供大家参考。

具体实现方法如下：

using System;

using System.Configuration;

using System.IO;

using System.Threading;

namespace FQDService.Utils

{

    /// <summary>

    /// 写日志类

    /// </summary>

    public class FileLogger

    {

        #region 字段

        public static readonly object _lock = new object();

        #endregion
        #region 写文件

        /// <summary>

        /// 写文件

        /// </summary>

        public static void WriteFile(string log, string path)

        {

            Thread thread = new Thread(new ParameterizedThreadStart(delegate(object obj)

            {

                lock (_lock)

                {

                    if (!File.Exists(path))

                    {

                        using (FileStream fs = new FileStream(path, FileMode.Create)) { }

                    }
                    using (FileStream fs = new FileStream(path, FileMode.Append, FileAccess.Write))

                    {

                        using (StreamWriter sw = new StreamWriter(fs))

                        {

                            #region 日志内容

                            string value = string.Format(@"{0}

--------------------------------------------------------

{1}
", DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss"), obj.ToString());

                            #endregion
                            sw.WriteLine(value);

                            sw.Flush();

                        }

                    }

                }

            }));

            thread.Start(log);

        }

        #endregion
        #region 写日志

        /// <summary>

        /// 写日志

        /// </summary>

        public static void WriteLog(string log)

        {

            string logPath = ConfigurationManager.AppSettings["LogPath"] + "\\FQDService_Log.txt";

            WriteFile(log, logPath);

        }

        #endregion
        #region 写错误日志

        /// <summary>

        /// 写错误日志

        /// </summary>

        public static void WriteErrorLog(string log)

        {

            string logPath = ConfigurationManager.AppSettings["LogPath"] + "\\FQDService_ErrorLog.txt";

            WriteFile(log, logPath);

        }

        #endregion
    }

}

希望本文所述对大家的C#程序设计有所帮助。
